 ### VAR.PdfTools
 Add the resulting assembly as reference in your projects, and this line on code:
 
-	using VAR.PdfTools;
+```csharp
+    using VAR.PdfTools;
+```
 
 Then extract the contents of a data column using:
 
+```csharp
     var columnData = new List<string>();
     PdfDocument doc = PdfDocument.Load("document.pdf");
     foreach (PdfDocumentPage page in doc.Pages)
     {
         PdfTextExtractor extractor = new PdfTextExtractor(page);
-        columnData.AddRange(extractor.GetColumn("Column"));
+        columnData.AddRange(extractor.GetColumnAsStrings("Column"));
     }
-    
+```
+
 Or the content of a field (text on the right of the indicated text):
 
+```csharp
     var fieldData = new List<string>();
     PdfDocument doc = PdfDocument.Load("document.pdf");
     foreach (PdfDocumentPage page in doc.Pages)
     {
